Chapter 8.1

Friday's class was supposed to be test day but plans change. No worries though, no time was wasted. We immediately started chapter 8.1. The class went through the chapter on that site mr. k said to go on. He was also right about the chapter being not so difficult. It was all about antidifferentiating velocity.

The only new stuff was total distance traveled. Our math book gave a good explanation of this. For example, if you take 5 steps forward and 3 steps back the net change would be 2, however the total change would be 8! So we learned to find total change we'd need to use absolute value sign. We also have to find the interval where the velocity is positive and negative and antidifferentiate them. We then add those them together to find the total distance.

Yes...that is my scribe post. Next scribe will be benchi-man. I'm not really sure what to tag this as...........
